, z claims. (ci. ics-12s) This invention relates to improvements in auxiliary window construction more particularly of the class wherein an auxiliary trame is provided. exteriorly of a conventional window, into which frame other window sashes may be inserted from the inside of the building such sashes selectively comprising glass inserts to provide storm pro tection or screen inserts to provide protection against insects, or one of each, ii desired.

I amaware that auxiliary frames have been provided heretofore, for substantially permanent installation, against the exterior face of conventional window frame constructions. However. such auxiliary constructions have proven inefilcient, complicated, and unsightly, despite a persistent demand for some type of practical construction embodying a combination screen and storm frame whereby sash inserts oi comparatively small dimensions, capable of easy storing and handling, and insertable from within a building may be used.

-Among other objects, my invention aims to provide an auxiliary frame and sash insert construction which is markedly simple and eillclent in construction and operation, and which at the same time does not detract from the appearance of the window.

The invention will be understood by reference to an exemplary construction shown in the accompnying drawing. in which- Figure 1 is an elevation ofthe interior o! the auxiliary window frame with storm sash inserts therein, and being a section taken on the line i-i of Fig. 2 somewhat reduced showing a movable closure in closed position, in lull lines, and in open position in broken Lues;- A

Figure 2 is an enlarged cross-section taken on the line 2 2 of Fig. l, and showing also. somewhat diagrammatically, the conventional window of the building;

' Figure 3 is a fragmentary plan view taken on the line 3-3 of F18. 1 but with the movable closure in open position; and

Figure 4 is a fragmentary cross-section otherwise similar to Fig.'2 but showinz.v a screen sash insert employed with the auxiliary frame. with which screen insert a movable closure is not necessary.

Referring in details to the drawing, it may be remarked that in one conventional form oi win dow construction, the main window frame it is well known, having the usual channels il and i2 for the usual lower pane il andupper pane i3 of the window respectively. Overhanging the frame lli may be a brick coping i8 and at the l side runners 2l, suitably corners of the frame.

bottom oi the frame the usual stone sill l0 may be employed.

In accordance with the present invention. I have shown applied to the exterior of this conventional window frame construction, my improved auxiliary lrame il which is rectangular to ,conform to the size and shapeA of the window opening on the exterior of the building, and which may have s. top piece Il, a bottom piece i9, and secured together at the As here shown. the frame i1 `is snugly received into the window opening to abut marginal stop 2| ot the main frame Il at the top and sides of the window and the body o! the main frame il itself at the bottom of the window, thus resting, for example. on the stone sill. For appearbe a permanent or so More particularly in accordance with the pres- 35 less height ent invention and to accomplish the purposes Just referred to, the bottom piece Il oi' my improved auxiliary frame. as will be observed from the drawing, is advantageously of substantially than has heretofore been employed in auxiliary frames of this class, and it termi hates substantially below the bottom piece 23 oi the conventional lower sash for the pane it `oi the window. This is made possible, for

4o one because I have here shown a ventilation slot 24 admitted into the extreme lower exterior edge of the bottom piece is of the auxiliary trame rather than into en intermediate portion or the frame, thus eliminating the necessity -i'orta portion oi the bottom piece i9 to extend below the slot.

The alot it, i: as at Wi and y. ...aantasting with an opening in the interior margin of the auxiliary frame. Sit may be ativan tageously iori'ned in a sill-plate 2l extending along the lower margin o! the frame between side runners 2l and which may be permanently fastened to the trame bottom piece il. as by nails or the like W, to slightly overlap the conveninstance. is shown angulartional window frame I0. Let into the lower surface of the siii-plate 21, I have shown a foraminous partial closure for the opening 26 which may be a wire mesh 29 fine enough to prevent the ingress ofinsects but at the same time permitting drainage of water or other moisture therethrough, either as a result of rain or snow nding its way into the space between the auxiliary window frame and the main window, or as a. result of washing oi.' the window or window sill.

It will be observed that thus far I have described my improved auxiliary window construction as it is comprised without the employment dow. and withdrawn through the space normally occupied by the lower main window rame Il. which at this time may be raised in the usual manner. Also, thereupon the lower sash 3| may be removed similarly. y

To retain the sash inserts in position as described, turn-buttons or the like may be provided. for example, as at I2 on the inner face of the auxiliary frame I1 and rotatable as on fastener screws 43. Both to prevent interference of y these turn-buttons with the stop 2| of the main therein of the insert sashes 30 or 3| shown in liigs. 1 to 3 of the drawing, or the insert sash 32 shown in Fig. 4 of the drawing, and as it may be during, say, intermediate weeks oi' thev spring or autumn when no inserts next described may be necessary. With the approach of the colder weather of winter, however, it becomes customary and desirable to provide for additional protection against storm and cold, and to'prevent undue heat losses through the main window panes, and at this time insert sashes I0 and 3| L may be advantageously employed.

The insert sash 30 is shown as the upper anxiliary sash and the insert sash 3| as the lower auxiliary sash. These being of relatively small dimensions, that is, each substantially half of the size of the auxiliary frame I1 itself, may be easily' stored and handled and inserted into the auxiliary frame I1 from the inside oi' the building. making lt unnecessary to expose the person to the outside weather or to the hazards of stepladder climbing or the like.

In order to simplify the construction of these insert sashes and 3|, I have shown them comprised principally of simple rectangular frame members 33 which may be lappingly abutted I against the rectangular nance part 34 of the auxiliary frame i1. By this construction, the weather stripping 35 may be carried by the outer margin of the sash frames 33 to abut the ange 34, thus making it unnecessary for the sashes to t tightly at their edges and providing a tolerance space 36 at these edges to allow for swelling or shrinking of the sashes themselves or for settling of the building with consequent perhaps slight distortion of the permanent auxiliary frame I1. To act as a rain deflector, the lower sash 3| may carry a deflector piece 31 letinto the sash frame member 33 at the bottom of the sash 3| upon the exterior side thereof and adapted to overlie the auxiliary frame ange 34 to close the space 38 between the frame and the sash at this point.

As will be vreadily seen from the drawing, the insert sashes 30 and 3| may be provided, at the parting line between them, with short mating flanges 35| on the upper sash 30, and 40 on the lower sash 3|, the flange 39 of the upper sash being outermost of the window, and the :lange 40 of the lower sash being innermost thereof. By-

spacing these flanges apart laterally as best shown in Fig. 2, weather stripping 4|, desirably carried by the upper sash 30, may be disposedbetween the sashes. Also, by making these mating flanges 39 and 40 relatively short as shovm, the upper sash 30, when desired td be removed,

. may be readily swung a short distance inwardly window frame and to suit the reduced thickness of the insert sashes, recesses 44 in the inner edge oi' the auxiliary frame I1 may be cut for the turn-buttons. A similar turn-button I5 may be provided on the upper insert sash 30 and fastened as by screw 46 thereto adjacent the parting line between the insert sashes 30 and 3| and adapted to be turned to secure the sashes together at this point.

It will of course be understood that the insert sashes 30 and 3| just described, as storm sash may carrythe usual glass panes 41 for this purpose. and in order to substantially completely close the ventilation opening 2s in the auxiliary frame when desired, the lower insert sash 3| is here shown carrying a closure 43, in this instance in the nature ci a wood flap pivoted at one end as by the pivot screw 43 to the lower insert sash frame piece 33 by the screw 50 and swingable toward and away from the openingfas shown by the arrow 5 I.

Since the closure I8 is shown pivoted so that in one position it is flush with the lower edge o1' the frame piece 33, and just to one side of the opening 26, the closure in closed position, as shown rin full lines in the drawing, lies snugly over the ing 28 is substantially and entirely closed against A the entrance oi! any appreciable cold air, for example, into the space between the auxiliary window frame and the main window. When it is desired to admit air from the outside into the building, however. the main window pane Il may of course be rst raised, and thereupon the closure 48 may be swung upwardly on its pivot 48, as shown in dotted lines in Fig. 2, where it will be maintained 'by friction with the screw 50 until desired to be again closed.

In the summer months when flies and mosquitoes are numerous, instead o1' the sashes 30 and 3| with the glass panes 41 therein, insert sashes such as shown at 32, Fig. 4, may be employed, without any change being necessary in the auxiliary frame I1, the insert sashes 32 having the usual screen covering 52, which takes the place of the glass pane 41. At this time no closure is necessary for the opening 28, since air is admitted freely into the space between the auxiliary frame I1 and the main window frame I0 through the screens 52, and at the same time if rain enter therebetween it may readily .run down through the opening 26 and out through the slot 24, which, being admitted into the extreme. lower edge of the auxiliary frame I1, provides efficient drainage means.

So constructed and arranged, I have provided an improved auxiliary window construction in which the insert sashes are set back from the farthest exterior o! the auxiliary frame accomplishing the purposes both of providing an enhanced weather-tight construction and also of improving the appearance of the window from the exterior of the building, it being recognized that set-backs of building parts add interest to the eye of the beholder and break the monotcny of plane surfaces which have been so often characteristic of storm windows in the past. Furthermore, the insert sashes may be easily removed through the lower main window opening without necessitating the lowering of the upper main Window, which is frequently objectionable due, for example, to the increasing use of Venetian blinds or other interior decorative elements.

Such changes may be made as fall within the scope of thefollowing claims without departing from the invention.

Having described my invention, I claim:

1. In a window construction of the class described embodying an auxiliary frame surrounding a window exterior and a plurality of removable interchangeable Window inserts for said frame one being a summer insert carrying screen and another a winter insert carrying glass, that y improvement therein wherein the frame has a combined ventilation and' drainage slot provided in its extreme lower exterior edge and communieating with an opening in the interior of the frame oiiset from the inserts, a foramlnous elo sure for said opening ,fixed in said frame, and pivoted ap closure for said opening adapted te selectively cover or uncoverl said opening while permitting ready interchangeability of the in., serts.

2, In a window construction o the class described embodying an auxiliary frame surrounding a window exterior and a plurality of removable interchangeable window inserts for said frame one being a summer insert carrying .screen and another a winter insert carrying glass, that improvement therein wherein the frame has an outlet slot in its `lower exterior margin and communicating with an opening in the interior margin of the frame, a fcraminous closure for said opening fixed in said frame, and a nonforaminous closure for said opening carried by the said winter Window insert and movable adjacent the frame to cover or uncover said open* ing when said winter insert is positioned at the slotted end of the frame, whereby the non-craminous closure may be removable with winter insert.
